That's not even remotely true.

The Quantum Fund by Soros and others, returned upwards of 30% per year for over three decades.

Steve Cohen averaged near 30% annual returns for two decades.

Buffett's investing track record is similarly off the charts.

And lastly, a monkey couldn't do what John Paulson (or Burry and Eisman) did with the 'greatest trade ever,' producing a radical outcome from an extremely intricate concentrated investment (some of which required them goading the opportunity into existence to begin with).

If you had said monkeys with darts can sometimes outperform the bottom half of traders on Wall Street, you might have been close.

30% returns per year for over three decades? Impressive. I wonder how much of that was attributed to insider information.

How is this down voted? Steve Cohen is practically synonymous with insider trading in the modern era.

Using Steven Cohen as an example only hurts your argument. His success has nothing to do with strategy and everything to do with insider trading.
